To all whom it may concern:

Be it known that we, Pio'rn JARNUSZKIE wroz, LUCJAN Gnarinnowsni,STANIsiAw SzoznsNY, LUDWIK CHYBoZYS'sKI, subjects of the Czar of Russia,and residing at \Varsaw, Russia, have invented certain new and usefulImprovements in Disconnectible Metal Bedsteads, of which the followingis a specification.

Our invention relates to disconnectible metal bedsteads.

Bedsteads which cannot be taken to pieces and each of whose sidescomprises two tubes which are integral with the front and rear ends ofthe bedstead are well known. In metal bedsteads which can be taken topieces, however, it is very diliicult to connect these sides, which areformed of two tubes or rods of various section, in a dust-tight mannerand without slots, to the other parts of the bedstead. When each sideconsists of only one rod, it has been attempted to make a suitable jointby specially shaped castings, but this has the disadvantage, on onehand, that the weight and cost of the bedstead are considerablyincreased and, on the other hand that, in spite of the use of thesecastings, a rigid connection cannot be obtained.

A primary object of our invention is to obviate these defects. To thisend, we pro vide a bedstead in which the sides, each of which comprisestwo rods, preferably tubes, are attached to the front and rear ends ofthe bedstead by means of cross-pieces which carry short tubular members.These tubular members are connected in a dust-tight manner and withoutthe use of slots, by means of tubular nuts, and screws welded to theoutside tubes of the ends of the bedstead. The employment of speciallydesigned castings and the like is thereby completely obviated, the tubesat theend of the bedstead do not require to be drilled, nevertheless theinclividual parts are attached in a dust tight manner and without theuse of slots.

One illustrative embodiment of our invention and a modification thereofis represented by way of example in the accompanying drawing, wherein:

Figure l is a perspective view showing a. preferred form of our improvedbedstead, and Fig. 2 is an elevation showing the connection of onesidewith one end; Fig. 3- is like view of a modified form of connection;Fig. 4 shows a key.

Referring to the drawing, the front and rear ends of the bedsteadcomprise the sup ports or feet 1 which are braced by stays 2. Across-bar 3, which may be curved, is welded, preferably autogenously, atthe height of the mattress to the members 1 and 2 and is provided withholes into which the hooks of the mattress take. In addition, screwbolts5 are welded to the members 1. Each side of the bedstead comprises twotubes 6 which are stiffened in the middle, preferably by onecross-member 7 and are connected one with another at the ends byconnecting members 8. These connecting members 8 may be eitherrectilinear (Fig. 3) or curved (Fig. 2). Each connecting member has twotubular branches 9 for surrounding the bolts 5. Tubular nuts 1.0 arescrewed on the bolts 5 in the branches 9 by means of the key shown inFig. 4 so that the sides are connected dust-tight and. without slotswith the ends of the bedstead. In this embodiment, the nuts enter thetubular members. In this manner the described disadvantages of knownbedsteads are completely obviated, because owing to the describeddust-tight connection of the individual parts of the bedstead with oneanother, dust and the like cannot collect at the places of junction.

e have shown a preferred embodiment of our invention, but it is obviousthat changes can be made in the details thereof without departing fromthe spirit, as set forth in the following claims.

We claim:

1. Ina disconnectible bedstead the combination with a vertical endsupport, of two screws welded thereon, a side rail for the bedsteadcomprising two rods and a transverse member connecting the ends of saidrods, said transverse member having tubular members at the ends thereofnormally surrounding said screws, and tubular nuts normally screwed onsaid screws and entering into said tubular members.

2. In a disconnectible bedstead, the combination of an end piece, a siderail normally attached to said end-piece, projections on said end-piece,and tubular members at the said projections and coact therewith, andafastening means adapted to be mounted on i each of said projections andto close the open ends of the said tubular members, the

said tubular members closeiyfitting 0n the 15 projections 01": said endpiece.

In testimony, that We claim the foregoing as our invention, We havesigned our names in presence or" two subscribing Witnesses.
